What is the role of water in compaction?


·  What is the role of water in compaction?

Moisture content plays very important role in densification of soil.

When the moisture content is low, the material is stiff and difficult to compress and the dry soil density is low , when the moisture content is increased, soil particles are lubricated and the soil becomes soft, plastic and easier to compaction. Thus, the dry soil density increased and reaches a maximum.

problem:- A circular tank of diameter 4m contains water up to a height to 5m. Orifice of diameter 0.5m at the bottom. Find the time taken by water:- 1. To fall from 5m to 2m 2. For completely emptying to tank take cd=0.6

what is venturi flume - Campare venture meter and orifice meter.

Campare venture meter and orifice meter. Venture meter:- A venturi meter is a tool used to measure the flow rate of a pipe fluid. It cosist of three parts- (1). A short converging part (2). Throat (3). Diverging part It is based on the principle of bernaulli’s equation. Orifice meter:- It is an instrument used to measure the fluid flow rate through a pipe. It's cheaper than a venture meter device. It also operates in the same way as the venture meter principle. Venture flume A venture flume is a critical flow, open flume with a restricted flow, resulting in a fall in the line of hydraulic grade, producing a critical depth. It is used in very high flow rates flow measurements, generally provided in millions of cubic units.
